Abstract
The bonding possibility of the double oxide film defect was investigated by holding pressure during solidification after holding in liquid A357 alloy for 13 min. The defect was modeled experimentally through contacting the oxide film layers of the A357 alloy. The composition and morphology of the oxide film layers were studied by SEM and EDX. The results show that the bonding area of the oxide layer increased with the holding pressure during solidification. This is due to the extrusion ability among the porous spinel gets stronger with the increase of holding pressure, which means the liquid metal, could flow through the porous spinel much easier.
